Step 1: Construction

first remove plugs on side of cooler - they pop out to reveal the Phillips screws that hold the tilting cover on, once these screws are removed then set aside.

cooler top then is easily removed - grab a empty beer case to use as a temporary stand

next step is mount any quality pair of speakers to side using counter sunk hardware if possible to not cause interference when opening and closing - (depending on speakers chosen, using predrilled wood screws would do) see pic for location and far forward the front the better to leave enough room for the Batteries

how long will the battery charge last on this?

Hi there- the gell cells are 7 amp/hr each so after a 4hr charge or so the radio should last 14hrs at good volume, the batteries I got for free because they were old but so far I have left it on outside all day a few times and seems to never run out..if I had money I would get the lithium ion pack on amazon thats 14 amp/hr and weighs only 1.5lb @$80.00
